MEAD E.-GOODIIUE, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO FEATHER DUSTER (10.,

CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

FRAME FOB WALL-BRUSHES.

Specification of Letters Patent.

To all whom it may concern."

Beit known that I, MEAD E. GoonHUE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Frames for Wall- Brushes, of which the following, when taken in connection with the drawing accompanying and forming a part hereof, is a full and complete description suflicient to enable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to frames over which lambs wool is sewed to make brushes used for dusting hardwood floors, walls, ceilings and the like. And the object of this invention is to obtain an economically made, flexible and resilient frame, to which a handle can be attached; a frame which will be durable and one which will retain its resiliency for a considerable time, when used.

A further object of the invention is to ob tain a frame which in use will remain substantially flat on the front edge thereof and thereby force the lambs wool, or other covering thereof, against the object wiped thereby.

I11 the drawing referred to Figure 1 is a front elevation of a frame embodying this invention. Fig. 2 is an end elevation of a frame embod ing this invention. And Fig. 3 is a vertica sectional view on line 33 of Fig. 1, viewed in the direction indicated by the arrows.

A reference letter applied to designate a given part is used to indicate such part throughout the several figures of the drawing wherever the same appears.

A is a socket provided with internal screw threads which are indicated b broken lines in Fig. 1 of the drawing and ettered a. A handle having corresponding screw threads may be attached to socket A, by turning the screw threads on the handle into the screw threads (1, in the socket, in the usual way of attaching handles to sockets.

B is a wire, bent at b, b, b, and b, which is put through the hole (O) provided therefor in the socket A, (as is indicated by broken lines in Fig. 1), and the ends joined, as at D.

E is a wire bent at e, e, and ut through the hole F provided therefor in'tl ie socket A, (as is indicated by broken lines in Fig. 1), and

attached to the wire B at f, f, by bending the ends G, G, over the wire B. The wire B is provided with bends at f, f, where the ends G, G, of wire E are bent thereonto, as described, to prevent a sliding or slipping movement of wire E on wire B.

Wire B, when bent up as described forms a rectangle, and the wire E is attached to wire B in such manner as to draw the sides H, h, of the rectangle out of a straight line, (as lines I, i). The wire E is, by this construction, put under tension, and the resiliency thereof tends to maintain wires B and E in the position illustrated in. Figs. 1 and 2; and

when the frame formed by such wires is forced into the position illustrated in Fig. 3 the wire B turns in hole Gin the socket, as on a fulcrum and the wire E turns in hole F in the socket as on a fulcrum; and hence, wire E will draw side H of the rectangle formed by wire B out of the curved line in which it would otherwisemove, say line J, towards the curved line 7' in which. the ends G, G, move; thus increasing the tension of the spring formed by wire B. The increased Patented Dec. 22, 1908.

tension of the spring B thus obtained tends to return the wires B and E into their initial lposition, and such wires are thus so returned y the resiliency thereof as the pressure thereon is relieved.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is,

1. A rectangular frame made of bent up resilient wire, a socket provided with holes therethrough, the frame and socket joined by one of the sides of the frame assing through one of the holes in the soc et, an

additional wire also passing through one of the holes in the socket, such additional wire bentup and the ends thereof turned over one of the sides of the frame, such frame,

socket and additional wire associated so that the longer sides of the frame are drawn out of a straight line by the additional wire; substantially as described.

2. A socket .rovided with internal screw threads in com ination with a wire bent up to obtain a rectangle and the ends of the wire joined, such socket provided with holes therethrough and one of the longer sides of the rectangle put through one of the holes in the socket, an additional wire put through the remaining hole in the socket and bent up to and connected with the remaining longer side of the rectangle, such additional wire arranged to draw the longer sides of the rectangle out of a straight line; substantially as described.

3. A socket provided with internal screw threads in combination with a wire bent up to obtain a rectangle, the ends of the wire joined and the wire on one of the longer sides of the rectangle bent to obtain an indenture,

such socket provided with holes therethrough and one of the longer sides of the rectangle put through one of the holes in the socket, an additional wire put through the remaining hole in the socket and bent up to and connected with the remaining longer side of the rectangle and at the indentured points thereof, such additional wire arranged 15 to draw the longer sides of the rectangle out of a straight line substantially as described.
